Kusintha kwa Hydrogen Production: Natural Gas vs. Methanol

Hydrogen, yonyamulira mphamvu zambiri, imadziwika kwambiri chifukwa cha gawo lake pakusintha kukhala tsogolo lokhazikika lamphamvu. Njira ziwiri zodziwika bwino zopangira haidrojeni m'mafakitale ndi kudzera mu gasi wachilengedwe ndi methanol. Njira iliyonse ili ndi ubwino wake ndi zovuta zake, zomwe zikuwonetsa kusinthika kosalekeza kwa matekinoloje amagetsi.

Natural Gas Hydrogen Production(Nthunzi reforming process)

Gasi wachilengedwe, wopangidwa makamaka ndi methane, ndiye wopezeka kwambiri padziko lonse lapansi popanga haidrojeni. Njirayi, yotchedwakusintha kwa mpweya wa methane(SMR), imaphatikizapo kuchitapo kanthu ndi methane ndi nthunzi pa kutentha kwakukulu kuti ipange haidrojeni ndi carbon dioxide. Njirayi imayamikiridwa chifukwa chakuchita bwino kwake komanso scalability, ndikupangitsa kuti ikhale msana wa mafakitale a haidrojeni.

Ngakhale kuti ili ndi mphamvu zambiri, kudalira gasi kumayambitsa nkhawa za mpweya wa carbon. Komabe, kupita patsogolo kwa matekinoloje a carbon capture and storage (CCS) akuphatikizidwa kuti achepetse zovuta zachilengedwezi. Kuphatikiza apo, kufufuza kwa kugwiritsa ntchito kutentha kuchokera ku zida zanyukiliya kuti apititse patsogolo kupanga haidrojeni ndi gawo lina la kafukufuku lomwe lingachepetsenso kuchuluka kwa mpweya wa gasi wa hydrogen.

Kupanga kwa Methanol Hydrogen (kusintha kwa nthunzi kwa methanol)

Methanol, mankhwala osunthika omwe amachokera ku gasi kapena biomass, amapereka njira ina yopangira haidrojeni. Njirayi imaphatikizapokusintha kwa nthunzi ya methanol(MSR), kumene methanol imachita ndi nthunzi kupanga haidrojeni ndi carbon dioxide. Njirayi ikukula kwambiri chifukwa cha kuthekera kwake kochita bwino kwambiri komanso kuchepetsa mpweya wa carbon poyerekeza ndi kukonzanso gasi.

Ubwino wa methanol umakhala pakusunga kwake kosavuta komanso zoyendera, zomwe ndizowongoka kuposa hydrogen. Khalidweli limapangitsa kukhala njira yabwino yopangira ma haidrojeni, zomwe zitha kuchepetsa kufunika kwa zomangamanga zambiri. Kuphatikiza apo, kuphatikiza kupanga methanol ndi mphamvu zongowonjezwdwanso, monga mphepo ndi dzuwa, zitha kupititsa patsogolo phindu la chilengedwe.

Kuyerekeza Kuyerekeza

Onse gasi ndi methanolkupanga haidrojeninjira zili ndi ubwino ndi malire ake. Pakali pano gasi ndi njira yotsika mtengo komanso yothandiza kwambiri, koma mawonekedwe ake a kaboni amakhalabe nkhawa. Methanol, ngakhale akupereka njira ina yoyeretsera, akadali koyambirira kwa chitukuko ndipo akukumana ndi zovuta pakukulitsa kupanga.

Kusankha pakati pa njirazi kumadalira pazifukwa zosiyanasiyana, kuphatikizapo kupezeka kwa chakudya, kulingalira kwa chilengedwe, ndi kupita patsogolo kwaukadaulo. Pamene dziko likupita ku tsogolo lokhazikika la mphamvu, chitukuko cha machitidwe osakanizidwa omwe amaphatikiza mphamvu za njira zonsezi akhoza kukhala njira yodalirika.

Mapeto

Chisinthiko chopitilira muhydrogen yankho(chomera chopanga haidrojeni) chimatsindika kufunikira kophatikiza magwero amagetsi osiyanasiyana ndikuphatikiza njira zatsopano. Kupanga gasi wachilengedwe ndi methanol hydrogen kumayimira njira ziwiri zovuta zomwe, zikakonzedwa ndikuphatikizidwa, zitha kuthandizira kwambiri pakusintha kwamphamvu padziko lonse lapansi. Pamene kafukufuku ndi chitukuko chikupitirirabe, njirazi zidzasintha kwambiri, ndikutsegula njira yachuma chokhazikika cha haidrojeni.
